LUBRICATOR.

Application filed January 25, 1919. Serial N oi 273,068.

To all whom it may concern:

Be it known that I, MARTIN A. ERNTSON, a citizen of the United States,residing at College Place, in the county of Walla Walla andState ofWashington, have invented certain new and useful Improvements inLubricators, of which the following is a specification. 7

The present invention comprehends generally improvements in lubricatorsand more particularly relates to a pressure operable lubricator.

It is the primary aim and object of this invention to provide a deviceof the above mentioned character designed with a secondary oil reservoirpositioned between the main oil reservoir and the condensation chamberwhile arranged therethrough is the condensation and steam conductor pipewhich acts as a heating medium for the oil in the secondary chamber andthereby maintains the oil in the secondary chamber ready for immediateuse.

It is an additional and equally important object of this invention toprovide manually operable valve means for controlling the flow orpassage of oil from the secondary chamber or reservoir to the mainchamber or reservoir, the secondary chamber being incidentallyprovidedjwith meansto permit of the filling thereof even'when the"lubricator is in use.

The invention also embraces the provision of=a device of the abovementioned character wherei'n' a drain valve is employed and connected tothe'bottomofthe main reservoir for draining cold water therefrom whilecoacting thlerewith is a removable plug in-the condensation chamberwhich permits of the filling ofthe condensation chamber with hot waterwhich is conducted to the main chamher or reservoir subsequent totheclosing of the drain valve for heating the oil in'the main' reservoirand in consequence permitting of the quick initial use of thelubricator.

It is a more specific object of this invention to provide a device ofthe above mentioned character wherein the gage for the main chamber orreservoir is of improved construction and is connected with the mainreservoir in a manner that will permit the attendant to observe the lastdrop of oil in the main chamber or reservoir; and to also provideimproved means for guiding the Specification of Letters Patent.

Patented Apr. 15, 1919.

The. invention is clearly illustrated in theaccompanying drawings, inwhich Figure 1 is a vertical sectional view of the improved lubricator,

Fig. 2 is a fragmentary elevational detail of a lower portion of thelubricator,

Fig. 3 is a transverse section taken through the connection between themain and secondary chambers or reservoirs.

Similar characters of reference are employed in all of the abovedescribed views, to indicate corresponding parts.

I Referring now, more particularly, to the accompanying drawings thereis provided a main oil chamber orreservoir 1 formed with a nipple 2 atone side and has connection with a'tubular support arm 3r A connectionblock 4. is cast from the top of the chamber 1 and serves as a supportfor the improved secondary oil chamber or reservoir '5. A condensationchamber 6v is' connected with the cap ofathe chamber 5 while leading tothe for instant useand'in order that the oil may be v forced fromthechamber or reservoir 1,in a manner hereinafter to become apparent,condensation and steam conductor tubes 10 are connectediwith the lowerportion of the condensation chamber 6 and is arranged through thechamber 5, the support 3, the connection 4 and the chamber 1 terminatingshort of the bottom thereof as indicated.

In order to permit of a quick and initial use of the lubricator, thebottom of the chamberis depressed and-the recess 11 is provided in turnwith an outlet opening 12 and formed on the under surface Witha valvecasing 13 in which is mounted a'manually operable valve 14 for coactingwith the opening 12 in controlling the passage of condensationtherethrough, the casing 1ncide'nta'lly being provided with another passage 1-3 for cooperatin -with the outlet opening 12 in allowing 1%16condensation to pass therethrough. When the condensation has been spentfrom the chamber or'r'eservo'ir 1, hot water is poured through thefilling opening 16 in the condensation reser vo1r '6 subsequent to theremoval of the plug '17 therefrom. A- manually operable plug valve 18'is mounted in the connection 4: "and controls the passage ofcondensation water orsteam through the pipes '10. It is of course to beunderstood that the valve 18 is left in a full-open position so that thedesired quantity ofhot water ma be placed in the chamber or reservoir 1.(in the other hand, when the plug 17 is ,mounted "in the opening and thevalve 9 is in an open po sition, 'the valve 18" is adjusted so as tocontrol the passage and condensation of steam ir'ito'the "chamber orreservoir 1 and in consequence regulating the'flow or passage of oilfrom' the reservoir 1 in a manner that V will hereinafter be described.

In order to permit of the depositing of the'oil'of the chamber 5 intothechamber 1 the connection 1 is-formed with-a vertical bore 19theendsof which communicate with the "chambers 1 and 5 while the manuallyoperable valve 20 serves'to control the'passage of oil therethrough,said valvefbeing normally left in a closed position until "such time as'it is i desired to use the oil in T the chamber5. In this "connectionit is "also to be observed that the chamber 5 which is provided witha'zfillin'g-opening 21 removabl'y; closed plug removed 'the;chamber maybe .filled with oil 'even when the lubricatorlisin .op-

Inorder to permit of the engaging ofthe oil as itis forced from thechamber or reservoir 1, a supporting bracket 25 is formed on the outersurface of the chamber 1 and V is provided with a bore 26 which isarranged in communication with the chamber 1 while the upper portion ofthis bore is enlarged to form a seat in which is fitted the lower end ofa gage glass 27 the upper end of which is arranged in communication witha hollow stem 28 the inner end of which is tion 4. This connection w than inverted recess with the casing ,35 -is fitted in the bracket"25--as-,-at 37,,This

A plug 32 is mounted in the top ofthe stem 28' near the closed outer "end thereof to facilitate theinsertion? and removal of the gageglass'27. By 'the"conr struction andarrangement just described it will be apparent that when .pressu're isapplied or when water formed by the condensation of the steam rises'i inthe :"chamber 1 the oilwill move upwardly someofit passing through thebore 26and rising through the tube or glass 27 thencepas'sing throughthe stem 28 while'the rest of the oil will pass upwardly into theinvertedrece'ss 81, it being apparent of course"-thatthe attendant willbe able to observe the exact amountof oil in "the chamber or reservoirto the last drop. p V

In order that the oil will be passed from the chamber 1 a verticallydisposed outlet suction tube 33 is arranged inthechamber, the upperportion being arranged within the recess 31 and in substantial alinementmunication with a laterally P-eX-tending fCZLSr ing35. A sight glass '36has its-lower. end fittedto and arranged in communication while theopposite end bracket 25 is also; formed with: azi'passage way 38 theinner end of which is'in c'om -mu.-

It is believed in view of the foregoing description that a furtherdetailed description of the operation of the invention is entirelyunnecessary. Likewise, it is believed that the advantages of theinvention will be readily apparent. Still further embodiments of theinvention than those herein especially defined may be resorted to asconditions or preference may dictate as may be in keeping with thehereto appended claims.
